DESCRIPTION
The output of the Left Brake low side
driver is shorted to +Vbatt.
DESCRIPTION
The Master Module (right controller) tem-
perature sensor is out of the permitted
range.
The Slave Module (left controller) tem-
perature sensor is out of the permitted
range.
The Master Module (right controller) has
reached thermal cutout.
The Slave Module (left controller) has
reached thermal cutout.
The right drive motor temperature is too
high.

SECTION 10 - DIAGNOSTIC TROUBLE CODES
• Check the left brake low side driver output CR3(4)
for a short circuit with +Vbatt.
• Check the brake coil for correct impedance (refer to
Section 8).
• If the wiring and the coil are correct, the driver cir-
cuit is damaged : replace the Slave controller.
• Change the Master controller.
• Change the Slave controller.
• Power down and allow to cool.
• Do not operate in ambients over 60°C.
• Check for jammed or obstructed right drive motor.
• Check for excessively high drive motor current con-
sumption while driving on the level ( over 120A ).
• Check for jammed or obstructed telescopic mast.
• Check for excessively high pump motor current
consumption while raising the jib with the platform
empty (battery output current over 90A).
• Check the Master module for proprer installation
(refer to § 8-4).
• If the module is cold when the fault appears :
replace the module.
• Power down and allow to cool.
• Do not operate in ambients over 60°C.
• Check for jammed or obstructed left drive motor.
• Check for excessively high drive motor current con-
sumption while driving on the level (over 120A).
• Check the Slave module for proprer installation
(refer to § 8-4).
• If the module is cold when the fault appears :
replace the module.
• Power down and allow to cool.
• Do not operate in ambients over 60°C.
• Check for jammed or obstructed right drive motor.
• Check battery charge and recharge if necessary.
• Check for damaged battery, power cables and con-
nections.
• Using the analyzer, check that the motor tempera-
ture sensor information is correct.
• Check the sensor wiring and connections.
• Check the sensor for correct impedance (refer to
Section 8).
• If the motor is cold and the fault is still present :
replace the Master controller.
